C220 CDi Diesel Injector question

[Baldrick123]

Just been told my MB dealer that all 4 injectors on my 53 plate C220 CDI are leaking. I took it in as it is very heavy on fuel, the car has done 80K miles. I have told them to go ahead as I need the car back, that was a quick £1,100!

I will ask them, but just wondered where the diesel leaks to? And I know you people will have the answer.

Brilliant forum by the way, by far the best.

Thanks in advance.

wow.. ALL FOUR were leaking??.. I can understand the odd 1 or 2.

Did you look around for companies that can remanufacture them?.. We certainly remanufacture diesel injectors, although it's not our specialty which we do on daily basis but definitely something we can do. - Just a note to yourself and others if anyone else has this kind of issue.

In regards as to where it leaks to.. I think it would depend on where along the injectors it was leaking, may leak into the chambers.. or just along the injector rail?.. No idea really because I've never seen the setup on the car.

Do they sell the injectors in singles as well or you have to buy all four?

 

[Baldrick123]

Unfortunately I didn't have time to look around and need the car back. The dealer said at 80k it wasn't unusual for this problem. I just took their word that all four were leaking.

I was sort of hoping that somehow the diesel leaked so that it exited the car as black smoke from the exhaust as this was also happening.

Thanks for your help.

This is another cheating exercise , all 4 thats crap.

MB send the injectors away and have them reconditioned, they charge a new price and keep your old ones, a rip off again

 

[Baldrick123]

Thanks Television, looks like I have been done!

 

[power-steering]

Yeah I couldn't believe it when you said all 4.. first time I've heard of this.. even for a dealer con!

This thread and I'm sure the 1000's others on this forum will contribute to helping others avoid such situations.

 

[power-steering]

Definitely!.. It's outrageous.. complain and see who can appeal to say that yes in all history of car repairs... 4 diesel injectors all cracked leaks at the same time!

leaking injectors

HI
Yes I would agree that its very unlikly that all four injectors have failed at the same time, what I would question is the heavy fuel consumption. If they were leaking (as in leak off) you would have poor or non starting, but you would not have heavy fuel consumption. If they are saying the injectors had failed and the nozzels were leaking this would be shown on DAS via quatity correction values at this point a printout would be taken and filed with the job pack, return to the dealer in question and ask to se the print for the "quantity correction values for your car this print should have the cahssis number of your car and the date printed if any of these details are missing it is not valid. Any value above +5 indicates a new injector is required any neagative values must be ignored. I have seen two or even three injectors failed at the same time and if the vehicle was of high mileage (100,000) a recomendation to change all injectors may be justified. In short ask to see the print out if only one injector was required ask for a refund.

As a final point the dealers do not send the injectors of to be reconditioned all injectors are purchased via MB UK and yes some are exchange units, meaning that we have to send the old ones back !!!!! that doesn't mean that the injectors fitted are reconditioned. I think MB do this to keep the injectors of the open market as failed injectors reflect badly on MB

TOP POST!!!!

In regards to your opinion of dealers selling reconditioned injectors.. I can't comment on this because I don't have the facts BUT I can safely say that we have many dealers ring us for steering components which of course we have remanufactured and given to them with 12 months warranty.

..That's not to say it's for their customers though.. :roll:

 

[Baldrick123]

Thanks for your replies everyone. I will ask for the printouts as suggested. I will also ask for the ould injectors to see what they say. If I get them and they are off any use to you let me know.

I had three go on My 02 C220 CDI at about 90,000. Tony Purslows provided the data sheets with the readings showing the leaking injectors.
Mine manifested itself by extremely lumpy tickover and vistually stalling whilst reversing and sat in traffic in gear.
A very Good indie near Portsmouth (Prestige) replaced 3 Bosch units for £550.

Injector leaks

Hope no-one minds me resurrecting this thread, but it seems quite appropriate for the problem I'm having with my car.

A few months ago I had an injector leaking; it developed a regular hiss and you could feel a blast of gas when the top covers were removed. The car also had a smell of exhaust gasses inside when driving. I didn't have any problems with starting or running; just the hiss and the smell. I had this repaired at an Indie that I use.

The problem has now returned. The hiss is not as noticable (yet?), but the smell is back, and, with the covers off, I can feel the gas and hear the hiss.

My W203 is approaching 140,000 miles and I don't have full service history so don't know if / when any injectors have been repaired / replaced. I wonder if the esteemed members of the forum would recommend just getting the injectors repaired one at a time as they give up (as seems to be what is happening), or ward off unforseen mishaps and have the lot replaced at once. Assuming I opt for the latter, what sort of mileage should I be able to expect before having injector trouble again?

Many thanks in anticipation.

This should not be all of them Andrew, you could be lucky and only have one faulty

 

[Cole@MBS]

You only need the seats cut and new seals and bolts, you dont need injectors unless your having starting/running problems!!

 

[Andrew23]

Many thanks for the advice, and the quick reply. Do you think it worthwhile getting them all done at once, or should I leave well alone with the other three?

 

[Cole@MBS]

Get the four seats cuts, and new seals and bolts.

 

[Andrew23]

Thanks again, SAM.

Boss has booked the car in - I'll give them a call and arrange to have them done.

 

[Alex Crow]

good advice from sam/colin. the time to replace the washers and bolts is when they are not yet leaking! so yes, do them all.

I would say it is a mathematical imposibilityfor all injectors to fail at the same time like when did you have 4 tyres all have a flat at the same time.
Injectors are made up from many componenet and the most inmortant piece is the injector nozzle.
The rest is the body or holder.
The body goes on for ever and the nozzle will wear our after time and start to give an uneven spray pattern and this will cause bad starting, running and sometrimes excessive smoke.
This does not mean you bin the whole thing you only have them serviced and new nozzles fitted, re searted in the head and new washers and bolt THE END.

Your car will if all else is up to snuff run like a new watch.
I had all 5 done for under £600 including removal, refitting new washers and bolts, ( washer and bolts my supply) and set up on the computer after now 110%.
MB are not worried about the injectors getting out to the general public they only want to make the big bucks by telling you they need replacing this is bull*h1t and all they want is MORE of your money.
Look for an independant fuel injection shop and ask them.
